- WALL CONSTRUCTION;

Application filed July 16, 1915. Serial No. 40,251.

To all whomiz't may concern:

Be it known that I, ARTHUR HARDoN- omm, J r., a subject of the Emperorof Aus-' tria Hungary, and resident of New York, borough of. Brooklyn,in the county of Kings and Stateof New York, have invented anImprovement in Wal1 Constructions, of which the following description,in connection with the accompanying drawings, is. a specification, likeletters on the drawings re resenting like parts.

y present mventlon 1s a wall construction for channel brick,particularly intended to enable a channel brick type of wall to be laidup at corners, and-is directed in part to certain I features of theinvention illustrated I a in my prior Patent No. 1,068,338 of July 22,

' 1913, but which could not be claimed therein, and of my copendingapplication, Se

.rial No. 40,250, filed July 16,1915.

Inconstructing a hollow wall wherein the air spaces or volds are formedhorizontally with an ,openpontinuous space throughout the length ofa-c'ourse, it is not feasible to use open ended brick at'corners as anopen end wouldbe exposed, and prior to my invention: no method ofbonding such channel brick and common brick headers was known orpractised. However, I have discovered a means of bonding and closing thehorizontal ends'of my channel brick with an overlapping header, whereby.such brick may be partly in the pier of each'corner, thusintegrallycarrying the channel brick into the corner piers, andpreferably having the side of one brick partially close the voids ofanother, vand requiring only a small filler or v header to close theopen end of the channel.

This feature is of especial importance in i that type of channel brickhaving raised projections on the-upper side which serve to interlockwith depending webs of the next superimposed row, such pro ections, ofcourse, being at an angle to each' other at each corner.' Ina squarecorner such projections will be at right angles and .would.

not permit being crossed and the corner block being on the same mortarjoint as the rest of the wall and of the corner pierconstruction; Atobtuse angle corners, such projections will be at a similar angle tothat of thecorner, as will readily be understood.

Other important features, details of construction, and advantages wlllbe hereinafter more fully pointed out and claimed.

Fig. 4: is a perspective of the ty e of channel brick illustrated in myen ing application, Serial No. 40,250, file July 16, 1915;

Fig. 5 is a furtherview of channel brick of the single channel. typeillustrated in said I pending application. 1

-Wh'le I have herein .illustrated'variou close the type shown in my-saidmodifications of corner construction wherein wherein such channel brickare carried partly into the corner piers or corner edges, thus utilizingthe hollow wall construction right in'to thecorners of the wall andobtaining all benefits and advantages in said corners of the horizontalair space construction, if

. desired.

The foundation isdesignated by the reference character 1 on which alower-mortar course 2 is laid, the type of channel brick illustrated inFigs. 1 and 2 being built thereon as shown at 3 directly into apart ofthe corner. Each endmost channel brick having the series of projections4: and 5. on the up per part, and the depending webs 6 on the lowerpart, may have said uppermost'proe jections readily knocked off by thehammer or the trowel of the workman, to provide a flat surface 7sufficient to receive the depending webs of the right angled channelbrick of the next course. As shown in Fig.

1, the channel bricks 8 have the uppermost projections partially removedto overlap the open ends of the channel brick at right an gles thereto,thus partially closing said voids and leaving the header block 9 tocomplete said closings. As illustrated in Fig. 2 these header blocks 9will be bonded at right angles to each other, each block closing a partof the channel in the right hand wing of the wall left partly open bythe overlapping of the endmost channel brick 8, and closing the entireend of such overlapping channel brick. The header 9 may be of hollowconstruction as illustrated in the drawings, or may be of solid brick,in either case the re moval of part of the raised portions or projections 4 and 5 enable the adjacent depending webs 6 of one brick to bebonded on the flat surface 7, and the header 9 to also be fittedthereon. As the channel brick of my invention are preferably of standardbrick size in height, the appearance of the corner; wall thusconstructed is identical with that of a solid brick formation and thuscarries out to the greatest extent the hollow construction into allcorners and edges.

In the type of channel brick illustrated in Fig. 3, a similar header 9is shown, the channel brick 12 therein shown, being formed with. onepair of depending webs 18 and 1a and a single pair of raised projections15 and 16, which latter are partly broken off to leave the flat space 17upon which the overlapping adj aoent brick and header may be fitted.

In the modification illustrated in Fig. i, a similar header 9 is shownfor the corners, wherein the channel brick 18 are formed with aplurality of raised projections 19 and 20 and depending webs 23. Theraised portions 19 and 20 are cut off, leaving the flat top part 21 andthe relatively thin tie portions 22. As there is no vertical strain onthese thin portions 22 they are sutlicient to hold the remaining halfportion of each brick 18, being also sufficiently solid to enable a partof the raised portions 19 and 20' to be thus removed.

Fig. 5 shows a still further modification of the type of channel brickillustrated in Fig. 4, and shown in my said co-pending application,wherein similar headers 9 are employed and each channel brick 25 has asingle raised portion 26, partly cut away to leave the projecting part27 of the top of each brick, where it juts into the corner or pierconstruction, smooth, to permit the depending webs 28 of the nextoverlapping brick to be positioned.

It will also be noted that the removal of the raised portions on the topof the channel brick, acts as a guide and interlocking for the dependingside web of the adjacent overlapping channel brick. in big. 1 forexample, the endmost brick 8 on the left wing with its depending web 6interlocking upon the projections of the lower full channel brick 3,also interlocks with theahutting ends of the raised projections 5 on theright hand lower brick 8, bemg firmly secured there1n by the bondingmaterial 29, and constituting a gage or stop for the next or topmostfull channel brick 3 on the right wing. This greatly facilitates cornerbuilding and the same advantage accrues in the construction shown by thevarious modifications of the other figures of the drawing.

While l have only illustrated the corner and interlocking projectionscould not nor-' mally be built uniformly level with the course, as theinterlocking means would prevent saine. Although ll prefer to remove thetopmost ribs or projections as illustrated in the drawings, it is alsowithin the scope of certain of the appended claims to remove parts ofthe depending interlocking means, 2'. e. the webs Whichcould readily becut by a trowel to span the space of a small rib without injury to'theload-carrying capacity of the corner. Such an arrangementwould obviouslybe' an equivalent construction to the preferred arrangement shown in thedrawings. The vital point of the invention is that channel brick are socombined at a corner where ordinarily the open ends would be exposed, tobe bonded with a header having plain sides and ends, such header partlyoverlapping and bonding the channel brlck 111 ad acent rows or coursesandsimultancously closing the openings.

having my channel brick of substantially standard brick size in height,an ordinary brick or brick pier can be used and a brick of each courseextended into overlapping bonding and closing relation with the adjacent channel brick course. Preferably, 1 er:- tend the channel brickcourses directly into the corner, but it will be readily appreciatedthat a solid brick corner pier with the headers extended therefrom intothe a Having described my invention, what it'll Ell claim as new anddesire to secure by Letters Patent is: l 1. Hollow Wall construction,comprising channel brick adapted to belaid horizon-'- tally, forminghorizontal open-ended air spaces, said brick having raised projectionsand depending webs adapted to interlock with adjacent courses, means forthe depending webs of one course to overlap the adjacent lowercourse atcorners while having said corner course level, in combination with aheader of standard brick size to close 'the open-ended air spaces-ofeach abutting to i brick laid horizontally forming a corner at a corner,with obstructing projections cut' oil from that part of the brick whichextends into the pier, and a header to close the open ends of abuttingchannel bricks.

3. Wall construction comprising two angularly disposed walls formed ofchannel which the alternate channel brick extend partially across andoverlap adjacent angularly disposed channel brick and a header fillingthe space formed between the ends of adjacent channelbrick and closingthe open-. ings in such ends;

4. Hollow wall construction consisting in channel brick interlocked vwith; standard sized brick, said channel brick comprising- .a horizontalbody portion having dependingwebs inclosing a horizontal air space onone side of said body portion which webs are of a substantially standardbrick size in outer exposed-area, raised portions on the opposite sidesof the body portion, so that the vertical height of the raised portionsand depending webs are greater than the height of said standard sizedbrick with which the channel brick interlocks, said channel brickhaving-a part of the raised portion removed.

at corners, whereby the depending webs and standard sized. brick arelaid flush in alinement at corners, piers,- and the like, and saidhorizontal air spaces are closed.

In testimony whereof, I have signed my name to this specification, inthe presenceof two witnesses.
